On September 22 it’s planned to send 1000 student projects built into PongSats (ping pong balls) to the edge of space.
These experiments and projects are made by those in kindergarten, university professors, high school science classes and home schools kids.

Projects range from plant seeds to filling a PongSat with a marshmallow. At 100,000 feet (30 km) the marshmallow puffs up completely filling the ball. Then it freeze dries. The student gets to hold in her hand the direct results of traveling the top of the atmosphere.
The launch of the PongSats will take place from the Black Rock desert in Nevada. The vehicles that carry them are called High Rack. They are made of foam and carbon fiber. There are four separate telemetry links to the High Rack tracking it during the flight. At the end of the flight the balloon is released and the High Rack descends by parachute.
It will take four High Racks, each with its own balloon to carry the thousand ping pong balls.

The balloon, appropriately called PIE1, was launched from Brightwalton, in Berkshire on July 14, 2012. The images were transmitted on 434.650 MHz (300 bps, 600 Hz shift) in the amateur radio 70cm band using the Slow Scan Digital Video (SSDV) standard.
PIE1 reached an altitude of 39,994 metres and images were received as far away as Northern Ireland (that’s over 500 km, not bad for just 10 mW on 434.650 MHz!).

Erin became interested in amateur radio after joining a club at her high school dealing with robotics and then ham radio-equipped high-altitude balloon launches. This school group has participated in FIRST Robotics competitions, and Erin has twice been Team Lead for Programming. The club also launches several high-altitude balloon missions each year, in a program called DREAMS. They have flown various scientific experiments as part of these missions, in addition to planning, building, and integrating radios, Global Positioning System (GPS) units and TNCs to track and recover the balloons. To facilitate these activities, the group’s sponsor, Luther Richardson, KI4AOJ, has encouraged the students to obtain their amateur radio licenses.
A subset of this group,including Erin, has participated in the Massachusetts Institute of Technology’s (MIT’s) “InvenTeam” competition, designing and building a portable lightning detector and early warning system. In addition, Erin re-started the Columbus High School Radio Club and served as its president for the past two years. The club was active in the 1950s and ’60s, and Erin’s great-grandfather (the original K4ETY) was one of its mentors at that time. The new club obtained the callsign W4CHS (Columbus High School) and has been active on the air.

Erin’s involvement with amateur radio and FIRST Robotics has helped fuel her interest in science and engineering. Last year, she applied for early admission to both Georgia Tech and MIT; she was accepted to both and will be attending MIT this fall.
Inside the shiny tube which contained Erin’s MIT acceptance letter was a note suggesting that the students “hack” their tubes, meaning to do something cool with them, in along-standing tradition of MIT hacks or stunts. Erin chose to send her tube to near-space.
Drawing on her ballooning experience,Erin planned, built, integrated, and tested a complete new tracking setup to fit into the very small shipping tube. The payload consisted of two GPS units, two custom-made antennas, one Argent Data OpenTracker+ kit (which Erin built), one handheld radio, and a fellow ham’s Byonics Pocket Tracker, a self-contained 100-milliwatt tracker/radio combination in an Altoids® tin. Erin also talked her mother into letting her use mom’s brand new GoPro Hero HD video camera.
With the assistance of a group of hams from the Columbus Amateur Radio club, Erin launched her balloon from Lumpkin, GA. A couple of hours later, she and the tracking team successfully recovered it, along with the complete HD video record of the flight. Erin took this video, as well as other photos and videos taken of the launch activities, and compiled it into an 8-minute presentation,complete with background music. She posted it to YouTube, and put a link to it on the MIT hack-the-tube site (see<http://tinyurl.com/ak4jg-space-video>). According to YouTube statistics, Erin’s video has been viewed thus far in excess of 82,500times.
This past May, Erin was invited to participate in no less than three forums and sessions at the 2012Dayton Hamvention®. These included the 25thanniversary “Youth Forum,” the “Ham Radio Town Meeting” and an “ARRL Expo”presentation where her video was screened.

An SSTV and crossband repeater payload developed by AMSAT-LU will be flown on a Glider and a High Altitude Balloon on March 3 and 17.
AMSAT-LU LU7AA report:
We are pleased to inform next Saturday March-3 2012 (if weather permits) from 12hs (GMT-3), Amsat-LU and friends will be flying from Zarate (Route 193, km 19 from Buenos Aires) an UV repeater including APRS + SSTV + CW + DTMF thru several flights aboard manned glider, as test for LUSEX (LU Satellite Experiment), being developed by AMSAT-LU.
Afterwards on Saturday March-17 from 12hs-LU on (GMT-3), a free Balloon will fly same payload from the city of Junin (Club of Gliders, Lagoon of Gomez), 250Km west of Buenos Aires City.
Payload will operate as an UHF to VHF crossband repeater, with CW tlm, APRS location and SSTV emissions in local and space frequencies.
According to estimates Balloon could reach 100,000 feet (30 km) in height, travelling from 50 to 100 miles towards east.
For these experiences, Amsat-LU works with and it is thankful to hams of Radio Clubs of Junin, QRM Belgrano, APRS Group, Don Bosco Ramos Mejia School, gliders Clubs of Zarate, Junin and Cañuelas, and the twelve Amsat-LU members development team as well as those who have actively participated and sent their reports in previous experiences.
Several flown experiments have been successfully operated during 2011 in manned-gliders, airplanes, captive and free Balloons allowing operational & practice for hams contributing to platform validaton of LUSEX satellite (LU Satellite EXperiment) on development by Amsat Argentina. More on http://lusex.org.ar
In order to monitor the payload (if you are within 400 miles of launch area) you need just an FM receiver either handy or base, in 145.950 for repeater and/or 144.930 for APRS. The repeater, that is activated via 123 Hertz subtone, operates receiving voice FM in 435.950 Khz (-112dbm, 0,56 uV) and emits with 2W the received audio live on 145.950 Khz.
Simultaneously APRS data will be sent in Packet at 1200 bauds in 144.930, and also in 145.950.
The DTI APRS symbol would change from a Balloon (/O) during the ascent to a glider (/g) during parachute descent.
Payload would operate as voice repeater activated by 123 Hz subtone during 1 minute, a warning bip at 40 seconds will indicate telemetry is coming, which is emitted if the repeater is not in use, if in 20 seconds more voice repeater still in use a two bips will be heard signaling that short APRS packages will begin in the different frequencies, also every 5 minutes CW (telegraphy with tones of audio) with CQ + callsign (LU7AA), sequence#, ext. and int. centigrade temperatures and voltage of batteries, after which the cycle will repeat.

Experiment for the first time in these flights will emit SSTV pictures in ROBOT-36 (36 seconds) in real time, showing what glider/Balloon sees. Every 5 minutes during ascent/descent and more spaced at high altitudes. (It can be received among others with MIXW, MMSTV & RX-SSTV ).
Payload would also carry on board two TV cameras (one towards earth and another towards horizon) recording video and sound during the flight. These captured videos could be recovered when payload is recovered.
APRS trajectory could be seen every minute, including speed, height, external and internal temperatures and 7.2v battery voltage using UI-View ( download from the UI-View official site on http://www.ui-view.org/ ) and/or to see/follow from Internet connecting to http://aprs.fi/?call=lu7aa-11 or locally via Packet at specified frequencies.
The experiment in 435.950 KHz besides voice, receives and accepts DTMF sequences commands on demand, I.E. sending B* (DTMF with handy keyboard on UHF) will return S5 … ….. in 145,950 VHF CW, reporting in CW signal strength received from your station, if S9+10 will returns P10.
There are also DTMF commands qualifying emission of CW tlm or APRS beacon or SSTV emission, commands that allows remote release of payload, mode changes, timers control, energy, power, etc.
Frequencies for previous coordination, announcements and flights will be 7090 Khz LSB +/-10 Khz and local repeaters.
During the flights will remain active wide coverage AMSAT-LU APRS Igate LU7AA-10 on 144.930 and 430.930 KHz, operating from the Constituyentes Investigation Center transferring whatever is received towards Internet.
For being an experiment oriented to a next satellite, the contacts made between stations via this payload will be considered valid for the recently announced permanent, gratuitous and applicable Satellite Certificate that AMSAT-LU and RClub QRM Belgrano grants, more info on http://www.amsat.org.ar/certsat.html
During the Balloon flight, amateur groups will chase the payload, aiming to locate and recover. Trapping ventures holds on this activity, as in the case of the Pampero 15 Balloon sent from San Miguel del Monte which landed in the middle of the Magdalena’s state prison … See http://www.lu5egy.com/Proyecto_pampero/vuelo_15/n_1esk.htm
All reports welcome. If you wish or can organize or want be part of control, or like to pursuit and recovery, or like operating and capturing data as an independent station, and/or wishes to join us personally in this adventure from the launching places email us to parapente at amsat.org.ar.
We appreciate reading of this information and thankful if distribution possible.
73, LU7AA, Amsat-LU, aiming at the future by making the present funny. http://www.amsat.org.ar/
